ROVlNG-TRAVERSE NIECHANISIVI.

SPECIFICATION forming part of Letters Patent Nou 637,020, dated November 14, 1899.

' Application filed June 22,1899. Serial No. 721,422. (No model.)

To all whom it may concern:

Be it known that I, OSCAR L. OWEN, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvementin Roving-Traverse Mechanism; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in mechanism vfor controlling the passage of the roving through the drawing-rolls of a spinning-machine; and it consists in the peculiar and novel construction and the combination of the cooperating elements whereby the path ofthe roving through the drawing-rolls is constantly changing and the extent of traverse may be regulated, as will be more fully set forth hereinafter.

Figure l is a rear view of my improved traverse mechanism. Fig. 2 is an end view of the same. Fig. 3 is a sectional view of the gears on a vertical line through the center of the same. Fig. 4 is a diagram showing the traverse of the lowest point of the roving-rod-operating lever at which the connecting-rod is secured, and Fig. 5 is a diagram showing the traverse of the roving-rod when connected as shown in the drawings.

Similar marks of reference indicate corresponding parts in all the figures.

In the drawings, A indicates the front beam, j

forming part of the frame of a spinning-mal chine; B, the rear drawing-roll; B the intermediate and B2 the front drawing-roll; B3 B3v B3, the top rolls; O, the roving-rod; C C', the trumpets on the roving-rod, and D a worm on the rear drawing-roll B.

The bracket E, supported on the front beam A, consists of the vertically-extending arm E and the obliquely-extending arm E2. To the arm E is adj ustably secured the standard E3, tothe upper end of which. is secured the stud E4, having formed integral therewith or Secured thereto at one end the pinion E5. The part E0 of the stud E4 forms the journal-bearing for the worm-'wheel E7, which engages with and is driven by the Worm D. The gear E8 is journaled in the worm-Wheel ET and engages with the pinion E5, which is stationary.

Part of the worm-wheel E7 is made thicker than the rest of the wheel, so as to secure a long bearing on the part E0 4of the stud E4 and a long bearing for the shaft E0 of the gear ES, as is shown in Fig. 3 and indicated in broken lines in Fig. 1. The stud E10 is secured to the side ofthe gear E8 out of the center of rotation, so that in rotating the gear E8 carries the stud E10 around its axial center. The pinion E5 is provided with ten teeth and the gear E8 with twenty-one teeth. This proportion may be varied, but the proportion should be uneven, so that the position of the stud E10 will be constantly changed by the rotation of the gear E8 on the stationary. pinion E5 as the gear is carried around by the Worm-wheel E7. Vith proportions of ten to twenty-one the stud E10 is losing half a tooth for each revolution of the worm-wheel, While with a proportion of ten to nineteen it would'gain half a tooth. The rod E11 embraces the stud E10 on one end and is adjustably secured by a screw-stud to the slotted arm E12 of the lever E o, pivotally supported on the stud E12, secured to the end of the arm E2. The upper arm E14 of the lever is also slotted and is connected with the roving-rod C by the screw E15, extending through the slot in the arm E14 into the roving-rod.

The operation of my improved roving-traverse mechanism is such that the worm D actuates the worm-wheel E7 and turnsV it once on any predetermined number of revolutions of the rear drawing-roll B and practically at each revolution of the worm-wheel imparts through the pivoted lever connected with the roving-rod C one complete reciprocation to the roving-rod. WVhen the rod E11 is connected with the arrn E12 of the lever, as is shown inthe drawings, twice the distance from the f ulcrum than is the distance from the fulcrum IOO ameterof the path of the stud E10, so that by changing the adjustment the extent of reciprocation may be varied, while by means of the eccentric position of the stud E10 and the difference in the proportions in the number of the teeth in the gear ES to the pinion E5 the terminal points in the reciprocation of the roving-rod constantly change.

, By the use of myim proved roving-traverse mechanism the wear of the roving on the drawing-rolls and the top rolls is distributed over the surface of the rolls and local wearing prevented, thereby materially increasing the durability of the top-roll covers.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a roving-traverse mechanism,the co mbination with the rear drawing-roll and the roving-rod, of a wheel loose on its supportingshaft, the supporting-shaft, a stationary pinion on the end of the supporting-shaft, a gear journaled in the wheel and engaging with the pinion on the supporting-shaft, a stud on the gear, the center of the stud being on one side of the center of the gear, connections between the stud and the roving-rod, and means for actuating the wheel; whereby reciprocating motion is imparted to the roving-rod, as described.

2. In a roving-traverse mechanism,a driven Wheel, a ixed shaft forming the support of the wheel, a gear journaled in and carried by the wheel, a pinion on the fixed shaft engaging with the gear, teeth on the pinion and teeth on the gear, the number of the teeth on the gear being more or less than a multiple of the number of teeth on the pinion, anda stud on the gear, the axial center of the stud being on one side of the center of the gear; whereby the position of the stud at each revolution of the driven wheel is changed, as described.

3. In a roving-traverse mechanism,the combination with the worm D on the rear drawing-roll and the roving-rod C, of the bracket E, the worm-wheel E7, the pinion E5 fast on the stud supporting the worm-wheel, the gear E8 journaled in the Worm-Wheel, the stud E10 secured to the gear on one side of its center, the relative number of teeth on the pinion and on the gear differing to cause a gain or a loss at eachrevolution of the Worm-wheel, a lever, pivoted on the stud E13, provided with the arm E14, connected with the roving-rod, and the slotted arm E10, and the rod E11 connected with the stud E10 and adjustably secured to the slotted arm E12; whereby the length of reciprocation is automatically Va- 'ried and may be adjusted to guide the roving over a longer or shorter portion of the rolls, as described.

In witness whereof I have hereunto set my hand.

OSCAR L. OWEN.
